Reiki is a Japanese holistic healing technique that channels universal energy through a practitioner's hands to promote relaxation, stress reduction, and overall well-being. Based on the belief that life force energy flows within us, Reiki aims to balance and harmonize this energy, fostering physical, emotional, and spiritual healing. It is a gentle, non-invasive practice that has gained popularity for its ability to enhance the body's natural healing abilities and promote a sense of peace and renewal.
